Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2,2,2-trichloro-1-(1-methyl-4-nitro-1H-pyrrol-2-yl)ethan-1-one (CAS 120122-47-6), a certified reference material (molecular formula C7H9Cl3N2O3, MW 275.52 g/mol) for analytical method development and quality control.
Structurally, 2,2,2-trichloro-1-(1-methyl-4-nitro-1H-pyrrol-2-yl)ethan-1-one (C7H9Cl3N2O3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 275.52 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
